Light-scattering characteristics of explanted opacified Aquasense intraocular lenses.
AIM To study forward light-scattering characteristics of calcified explanted intraocular lenses (IOLs) (Aquasense, Ophthalmic Innovation International Ontario). METHODS The amount of light scattered by the opacified IOLs was measured using a validated in vitro set-up for angles from 1.7 degrees to 22 degrees . This set-up gives results directly comparable with straylight values as valid for t...
متن کاملBlue light filtering intraocular lenses in phacoemulsification cataract surgery.
Blue light can damage retina and cause age related macular degeneration. After cataract surgery and lens removal retina stays unprotected. Blue light filtering intraocular lenses (IOL) increase protection of the retina. In our prospective study we investigated clinical results after bilateral implantation of Acrysof Natural IOL to 30 patients (N = 60 eyes). In a control group (N = 60 eyes, 30 p...
متن کاملValidation of a spectral light scattering method to differentiate large from small particles in intraocular lenses.
A psychophysical approach has been designed to measure straylight from intraocular lenses (IOLs) in vitro. This approach uses a clinical straylight meter (C-Quant) and an observer's eye as optical detector. Based on this, we introduced a method for study of straylight-wavelength dependency for IOLs. This dependency can be used to distinguish between 2 types of scattering particles (small and la...
متن کاملLight scattering in donor lenses
Light scattering for normal and cataractous lenses from 21-86 yr old donors was measured in vitro. As expected, scattering increased with severity of cataract. Scattering decreased with angle according to a power law. This corresponded to the power law finding for functional straylight measurements in early-cataract patients using white light (power around -2). In vitro, straylight increased mo...
متن کاملCost of cataract surgery after implantation of three intraocular lenses
BACKGROUND Posterior capsule opacification is one of the most frequent adverse events following cataract surgery. This manuscript reports the lifetime cost of complications linked to posterior capsule opacification using three types of intraocular lens with square edges. METHODS Costs were estimated from a retrospective study of patients who underwent cataract surgery and data from the litera...
